SWSCALE: Increase maximim with from 5120 to 21504

Heres a benchmark
VOFW 5120 VOFW 21504 Note
10438.8 10344.2 timex ffmpeg -y -i tulip2.mp4 tulip2.yuv
25611.9 24256.9 timex ffmpeg -y -itulip2.mp4 -s 1272x724 tulip2.yuv

25684.95 25387.675 average
This is on a Nehalem i7. Despite being a 500 frame, 720p video, the numbers
fluctuate, so I took an average of 4 runs.
Another reason I'd like this change is youtube accepts videos with higher
resolutions than 5120.
16384 is vp8's maximum resolution, so that should keep us amused for a
little longer.

Remove dependency from swscale-example.c to swscale_internal.h by duplicating
the necessary code. The duplicated code is a hack and should be removed once a
cleaner pixel format information system exists. swscale-example.c is example
code on how to use the library and therefore shouldn't rely on internal
headers.
